Embodiment Construction
[0021] The present invention is described in further detail below in conjunction with embodiment.
[0022] A kind of preparation method of 4-benzyloxyphenylethyl n-decanoate disclosed by the invention comprises the following steps:
[0023] A. Add methanol, p-hydroxyphenethyl alcohol and equivalent benzyl chloride into a clean three-necked flask, stir and mix evenly, then add solid sodium hydroxide in three batches, heat up to reflux after each addition and react for 0.5 hours, Then cool down to 50 degrees and add the next batch of sodium hydroxide, the reaction equation is as follows:
[0024]
[0025] B. After the step A reaction is completed, the solvent is directly distilled out, and then after the solvent is completely distilled, the equivalent of n-decanoyl chloride is directly added dropwise, and the temperature is controlled below 20 degrees. The reaction equation is as follows:
[0026]
[0027] C. After step B is reacted for 1 hour, a large amount of water is ...
